Frequently Asked Questions - RX1000 Rigol

How do I connect the RX1000 to a PC?

Connect the RX1000 to your PC using the provided USB cable. Install the USB Test and Measurement Device driver when prompted. Then install the RX1000 PC control software from the included CD. Start the software either from the Start menu or via Ultra Sigma.

How can I control the RX1000 without a PC?

You can control the RX1000 using a DSG3000 series RF signal generator. Connect the RX1000 to the DSG3000 via USB. On the DSG3000, press LF AUX and then RX1000 to access the control interface.

What is the purpose of the six switches (Sw1-Sw6)?

The switches route signals through different hardware modules. For example, Sw1 selects external or internal local oscillator; Sw2 controls the input from J2; Sw3 connects J3/J4; Sw4 controls mixer input; Sw5 controls low-pass filter; Sw6 selects VGA output.

How do I adjust the VGA gain?

In the PC software, click the text box under VGA and enter a gain code from 0 to 255. The output voltage gain (Av) depends on the code. For codes 0-127 (low gain mode) and 128-255 (high gain mode). Alternatively, use the VGA menu on the DSG3000 interface.

What are the typical applications of the RX1000?

Typical applications include testing frequency conversion, measuring band-pass filter characteristics, and evaluating the influence of amplifier or filter performance on the system. These require a DSG3000 signal generator and a spectrum analyzer.

What is the input frequency range of the RX1000?

The standard input frequency is 950 MHz ± 20 MHz. With expansion, it accepts 50 MHz to 1000 MHz. Input power should be ≤ 0 dBm.

Can I use the RX1000 with other signal generators?

The RX1000 is designed primarily for use with DSG3000 series generators. However, you can use it with any RF source within its input frequency and power specifications, but control via PC software is required.

How do I update the software or drivers?

Visit the Rigol website (www.rigol.com) to download the latest PC control software and drivers. Ensure Ultra Sigma is installed (version 00.01.05.05 or higher) before installing the RX1000 software.

What is the weight and power consumption of the RX1000?

The RX1000 weighs approximately 0.7 kg and consumes 1.5 W of power, supplied via USB.

What connector type does the RX1000 use?

All RF connectors are SMA (jack) type. The USB connector is a standard USB-B socket. The input and output impedance is 50 Ω.

Figure 4 Interface Layout of the PC Control Software

1. Resource Name and Connection Status

When starting the software via Ultra Sigma, the software displays the resource name automatically and the dropdown box is grayed out and disabled. At this point, the connection

status is √ denoting that the connection is successful. When starting the software via the

[Start] menu or shortcut on the desktop, the connection status is ✗; you need to click the dropdown box and select the resource name of the RX1000 connected to build the communication between the software and RX1000 manually. It takes some time (several seconds) for the software to search the resources and please wait for the resource list patiently. When multiple devices are connected to the PC, the resource names of all the devices will be displayed in the dropdown list and please select the resource name started with USB0::0x9906::0x2004 (all the resource names of RX1000 start with this character string).

2. Control Switches

After the software and RX1000 are successfully connected, you can control RX1000 via the software interface. There are six switches (Sw1, Sw2, Sw3, Sw4, Sw5 and Sw6) on the software interface and you can click the corresponding switch to control its state.

- Sw1: when J12 is connected, connect the external local oscillator signal input from the J12 terminal; when the J12 is disconnected, connect the internal 1 GHz local oscillator signal.

- Sw2: when J2 is connected, connect the signal input from the J2 terminal; when J2 is disconnected, amplify the signal passing through the band-pass filter or output it from the J3 terminal.

- Sw3: when J3 and J4 are connected, output signal from J3 or connect the signal input from the J4 terminal; when J3 and J4 are disconnected, amplify the signal passing through the band-pass filtering or the signal input from the J2 terminal.

- Sw4: when J5 and J6 are connected, output signal from J5 or connect the signal input from the J6 terminal; when J5 and J6 are disconnected, perform mixing on the signal passing through the amplifier or the signal input from J4 terminal.

- Sw5: when J7 and J8 are connected, output signal from J7 or connect the signal input from the J8 terminal; when J7 and J8 are disconnected, perform low-pass filtering on the signal passing through the mixer or the signal input from the J6 terminal.

- Sw6: when J9 is connected, output signal from J9; when J9 is disconnected, adjust the amplitude of the signal passing through the low-pass filter or the signal input from the J8 terminal and then output it via J10.

3. Adjust VGA

Use the mouse to click the text box under the VGA on the software interface and modify the value (gain code) in it. At this point, you can adjust the amplitude of the signal output from the J10 terminal (output voltage gain). The gain code of VGA can be set from 0 to 255.

Output linear voltage gain (Av) and gain code (Gc) satisfy the following relationship:

$$ A v = G c \times V e i n i e r \times (1 + (P G - 1) \times M S B) $$

Therein,

Veinier = 0.055744 V/V;

PG = 7.079458 V/V;

When Gc is from 0 to 127 (low gain mode), MSB = 0 ;

When Gc is from 128 to 255 (high gain mode), MSB = 1 .
